ter; conserve fertility of thesoilthrough the deposit and settling of valuable-mineral constituents which wouldjotherwise be carried away downstream; to impound water jfor V irrigation purposes; -to hold moisture over selected areas of soil; and to attain these ends through the use of specially-constructed 1ntakes for culverts located in roadway embankments or special fills where the fall of a water course is such that impounded water I spread back over the desired area.

With these and other ends in view, I illustrate in the accompanying drawing such in stances of adaptation. as will disclose the broad features of my invention without l miting myself-to the specific details shown thereon and described herein.

WVithin the experience of many agriculturalists, it has been noted that water courses having a more or less-rapid flow willin flood times spread over their bankscausing damage to the soil and growing crops forming lateral depressions, thus eroding the soil into deep ditches which in time will destroy the value,

The purpose of the gate is'to permit'of a rapid run ofi' of excess water. Should too great a depth of water stand on the protected area for too long a time the soil may become 7 water logged. To prevent this the gate 11 may be raised. or removed altogetherv thus its permitting the excess depth of water to flow away from the spillway 4.

a new water level will be secured.
